Welcome back to Sustainability Uncovered - the monthly show for anyone working in or passionate about environmental sustainability.

This episode is all about bio-based materials and what they could mean for the future of the built environment.

As businesses look for ways to cut embodied carbon and reduce reliance on fossil-based resources, materials made from renewable biological sources are attracting growing attention. But what are the opportunities and what challenges need to be addressed if bio-based materials are to scale?

We put these questions to our two expert guest speakers:

- Hannah Roughneen, R&D project innovation lead at Kingspan subsidiary STEICO

- Richard Broad, chief executive at the Alliance for Sustainable Building Products (ASBP)

Plus, the team looks at some of the biggest developments across the sustainability agenda, including the Climate Change Committee’s assessment of Heathrow expansion, the upcoming UN biodiversity COP and what to expect from COP31 later this year.

This episode is hosted in partnership with Kingspan.

Summer is in full swing (as is the UK's fifth heatwave in 2026 and third drought in five years). Amidst all the summer excitement, it can be easy to forget the impact some of our favourite activities have on the planet, from holidaying abroad to attending live events at home.

How are organisations already working to minimise the impact of the summer season? And what else is needed to unlock a greater transformation at scale?

The new episode of the edie Extra podcast is streaming now! Tune in as Ruth MacGilp, senior campaigner at global movement Action Speaks Louder, shares how the non-profit is putting pressure on one of the world's biggest activewear brands, lululemon, to decarbonise.

Last year, lululemon made over $11bn in profits, with its greenhouse gas emissions also growing 14% in the same period.

To get the attention of lululemon and encourage the company to move faster in cleaning up its supply chain, Action Speaks Louder launched 'mumumelon'. A dupe activewear brand, it aims to show lululemon that the same (or very similar) products can be made with a fraction of the carbon.

In April, Action Speaks Louder opened its pop-up mumumelon shop in Marylebone, London. Just steps away from an actual Lululemon Athletica store, the pop-up shop displayed a limited run of mumumelon garments – all made in renewably powered facilities where workers were paid the living wage.
